Custom Design Build St Louis

The owner of Hoffmann Brothers Mechanical Services, Robert Hoffmann, has his Professional Engineer license and is the lead Mechanical Engineer. We are one of the only companies in St Louis who is owned by a Mechanical Engineer. We have a competitive advantage in the industry because of Robert’s expertise and dedication to building and designing thousands of projects for St Louis area businesses for over 25 years. Hoffmann Brothers has designed, built and maintained thousands of HVAC design build projects, but we also can take on any custom design build job that your business may have. Here are some of the custom design build projects we have designed:

  • Hoffmann Brothers designed and built 2 aircraft electronic coolers for the Israeli Air Force. The hanger could be zero to 100F, but the unit had to put our 300CFM of 70F air. All electronics on the cooling system had to be 50Hz.
  • Hoffmann Brothers designed, built, and installed a dust collection system for a local manufacturing company. The dust collection system helped in the production of their product, because the mixture of the dust with their systems could change the color of the products in the plant.
  • Hoffmann Brothers designed and installed a dehumidification system for a Pharmaceutical company here in St Louis. The room had to be kept at 15% RH all year. We used a combination of mechanical refrigeration and desiccant dryers to achieve the customer’s needs.
  • Hoffmann Brothers Mechanical Contractors redesigned a clean room refrigeration system that had a $15,000 compressor failure each year. After our redesign, the system’s compressor has never failed.
  • Our team has custom designed multiple indoor pool facilities including all the heating and cooling, pool heaters, radiant floor heat, and dehumidification systems.
